After two months of drama, including the resignation of half of its board and the departure of the company’s top two leaders, the opera’s new board voted unanimously Friday to rescind the old board’s March 19 vote to shut down, it was announced Monday morning.

The San Diego Opera will have a 2015 50th anniversary season of “La Boheme,” “Don Giovanni” and “Nixon in China” in the Civic Theatre, and it anticipates having many more seasons beyond that.

“The community told us they wanted the opera,” Carol Lazier, the board’s new president, said at a news conference outside the Civic Theatre on Monday that was attended by several hundred cheering opera employees, singers, patrons, subscribers and board members. “There’s been an outpouring of support.”

Lazier and the opera’s board had set a condition of raising $1 million through crowdfunding by May 19 to avoid closure. The opera met that goal 10 days early, and last week surpassed the $2 million mark.

As of Monday — the deadline the board had set for deciding the company’s fate — the opera had raised more than $2.1 million in a primarily online drive involving 2,461 donors with gifts as small as $10 (the median gift was $100). Nearly half of those donors had never given to the opera before.

“The news from San Diego is tremendous,” said Marc Scorca, CEO of New York-based Opera America, which represents North American opera companies and had consulted with the San Diego Opera. “It demonstrates that motivated concerned citizens can work together to preserve an important cultural institution.”

Scorca credited a “an inspiring team of board members, donors, artists, technicians, staff and audience members” with charting a new path for the opera “that places creativity, collaboration and transparency at the heart of company operations.”

Lazier said Monday the board had raised an additional $2.5 million, which includes a critical $1 million gift she made in late March. That brings the total raised by the opera in a matter of weeks to approximately $4.5 million.

“That a broad swath of the community wants to come together ... many people who have not supported the opera in the past, financially, to do everything they can to save it is encouraging not only for the opera but for the entire artistic community, for everybody,” said Christopher Beach, president and artistic director of the La Jolla Music Society.
